        1. Read target prompt file from $ARGUMENTS

        3. **CRITICAL ANALYSIS** against research patterns:
           - Where do critical rules appear? (should be <15%)
           - What is max nesting depth? (should be ≤4)
           - What is instruction ratio? (should be 40-50%)
           - How many times are critical rules repeated? (should be 1x + refs)
           - Is there explicit prioritization? (should exist)
        4. Calculate component ratios

        ### Research Pattern Compliance
        - Position sensitivity: Critical rules positioned early ✓
        - Nesting reduction: Flattened structure (≤4 levels) ✓
        - Repetition consolidation: Single source of truth ✓
        - Explicit prioritization: 3-tier conflict resolution ✓
        - Modular design: External references for verbose sections ✓
        - **Note**: Effectiveness improvements are model- and task-specific
        
        ### Key Optimizations Applied
        1. **Critical Rules Elevated**: Moved from X% to Y% position
        2. **Nesting Flattened**: Reduced from X to Y levels
        3. **Instruction Ratio Optimized**: Reduced from X% to Y%
        4. **Single Source of Truth**: Consolidated Z repetitions
